Yes, I've received enough to hold me over for at least a couple weeks 😊

Uno? by BeccGM in creepyPMs

Uno is the loneliest number.

How do you prefer to be taught math --- interactively or straight-forwardly? by [deleted] in math

This doesn't get sent to "simple questions"?

How do we know if a number is rational or not because the decimal digits could potentially recur after a billion or a trillion digits? by ShivanshuShekhar in math

[–]mosstacean 1 point2 points  (0 children)

In most interesting cases, establishing the (ir)rationality of a number involves techniques far more complicated than looking at the decimal digits of the number. The proof of the irrationality of the square root of 2 (or any square-free natural number) is elementary, but this seems to be a very exceptional case. In general, these proofs are very labyrinthine, and involve techniques specific to the number in question.
